DEVICE FOR TYING KNOTS- Specification of Letters Patent.

Patented Aug. 28, 1906.

To all whom it may concern.-

Be it known that I, LEVI SILvEsTER OAR- DEN, a citizen of the UnitedStates, residing in the county of Orange and State of North Carolina,have invented certain new and useful Improvements in Devices for TyingKnots; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention is an improved knot-tying device adapted for use in tyingcord used for wrapping parcels; and it consists in the construction,combination, and arrangement of devices hereinafter described andclaimed.

In the accompanying drawings, Figure 1 is a side elevation of aknot-tying device embodying my improvements, partly in section; and Fig.2 is a detail view showing the mode of operation of the same.

The base 1 is adapted to be secured on a table or counter, near one ed ethereof, and is provided at its outer end wit an upwardlyextendingstandard portion 2, from the upper end of which projects anoutwardly-extending former 3, which terminates in a truncated cone 4.Said former is provided at a suitable distance from its lower side witha longitudinal bore 5, which is angular in cross-section and in whichoperates a similarly-shaped rod 6, which is provided at its outer endwith a hook 7. The inner end of the said rod projects beyond the innerend of the said former to a suitable extent and is pivotally connectedto the upper end of a lever 8, which lever is fulcrumed, as at 8, to thebase and extends downwardly therefrom, so that it may be readilyoperated by the foot or knee of the operator. A spring 10 is employed tonormally move'the rod 6 inwardly. Said sprin is here shown as anextensile spring placed on said rod and bearing between the inner end ofthe former and the upper end of the said lever. The function of the saidspring is to normally engage the hook 7 with the outer end of theformer-cone.

In the operation of my knot-tying device the two strings a b are caughtnear one end between the finger and thumb of the left knot.

hand. With the right hand the operator passes the string below the conedor tapered end of the former, around the same, back and upwardly overthe same, and then to the front. The operator then presses the lever byhis foot or knee to cause the hooked end of the rod to protrude from theend of the conical or tapered former, and the ends of the string in theleft hand are moved over the strings and placed so that the hook, bymeans of the spring, is caused to hold the ends of the string betweensaid hook and the reduced end of the former. The strings are then passedby the right hand around to a position at right angles to the axis ofthe former to form a loop which slips over the end of the former andalso over the hook, thereby forming a The sprin -pressed hook coactswith the outer end of the former to hold the ends of the string untilthe knot has been tightened, after which the ends of the string arereleased from the hook.

" Having thus described my invention,what,

I claim as new, and desire to secure by Letters Patent, is

1. A knot-tying device comprising a former, a longitudinally-movablehook-rod, a spring to normally close the hook of the rod against theouter end of the former, and a lever to move said hook-rod against thetension of the said spring.

2. A knot-tyin device comprising a base having a standar portion and aformer projecting outwardly from said standard portion, said formerhaving a tapered outer end and provided with a longitudinal bore, alongitudinally-movable rod in said bore having a hook at its outer endto engage that of the former, a lever fulcrumed to the base andconnected to said rod, and a spring to move the rod in the directionrequired to close said hook against the outer end of the former.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
